BACKGROUND

In floods or rainy seasons, the water in the city or the river is soaring due to excessive rain, which leads to traffic disruption or pedestrian trapping. In the past rescue operations, it is necessary to transfer people from the flood to the shore and need large-scale equipment such as pontoon bridges, fire ladders, assault boats as support. Large-scale machinery is used for rescue. However, in some special terrains such as wild mountain areas, large-scale machinery is difficult to reach, which not only causes inconvenience to rescue work, but may also miss the best rescue time. In the past rescue, in the face of large-scale machinery unreachable, fire-fighting ropes are usually used to connect rescuers and trapped people at both ends of the ropes. Rescuers or trapped persons move away along the fire-fighting rope. However, this method has certain hidden dangers and the need to consume a lot of physical strength during the process of travel. It is not suitable for the rescue of frail people such as old, weak, sick, and pregnant.
